Composite Pump Vanes

[arniep]

I am looking for sources for composite vanes for a sliding vane vacuum pump. I am hoping to find a supplier who is familiar with making vacuum pump or compressor vanes. I would appreciate any help.

Check Greenleaf ceramics.&nbsp;&nbsp;They have wisker reenforced ceramics that migh be very good for your application. Light, stiff, good bearing surfaces, chemical resistnace, etc.<br><br>Am I wrong, or is mass of the vane a good thing???&nbsp;&nbsp;Are you springing it out?<br><br>Larry<br><br>
